Tips

usage

嗪 is primarily a chemical terminology character used to transliterate the suffix -zine or -xine in drug and compound names (e.g. 氯丙嗪 chlorpromazine). It rarely appears outside scientific contexts.

Components

radical

口 kǒu

mouth

Left mouth radical, used here in its modern function as a transliteration marker, signalling that the character names a sound rather than a meaning. Modern chemistry uses 口-prefixed characters to coin transliterations of European technical terms: 吗 (-mor-), 啉 (-line), 嗪 (-zine).

phonetic

秦 qín

Qin (dynasty); surname

Right 秦 supplies the sound qín exactly. 秦 names the Qin dynasty (the source of the word "China" itself), but no historical sense is carried. 嗪 is a twentieth-century coinage transliterating "-zine" in chemistry names like 哌嗪 piperazine and 吩嗪 phenazine, pure pharmaceutical phonetics.
